Sample ID:	84Au-101
Station ID:	84Au-101
Latitude:	59.371569
Longitude:	-153.430727
Datum:	NAD83
Date Sampled:	1984-01-01
Sample Type 1:	Debris Flow

Text Description:
Boulder in lobate rubble flow (possibly 1883). Phenocrysts of plagioclase, hypersthene, augite, olivine, and Fe-Ti oxides, and pyroxenes. Olivine is altering to serpentine (?) along fractures and is surrounded by reaction rims of either fine grained plagioclase+pyroxene or intergrown Fe-Ti oxide+pyroxene
